SELF-LOADING MAGAZINE PENCIL.

Application filed April 1, 1921.

To all whom it may concern Be it known that I, ARTHUR B. TAY- Lon, acitizen of the United States, and a resident of Newark, in the county ofEssex and State of New Jersey, have invented new and useful Improvementsin Self-Loading Maga zinc Pencils, of which the following is aspecification.

This invention relates in general to pencils of the type comprising aholder or casing from which a length of lead may be progressivelyejected or propelled as the writing point wears away or breaks off. Moreparticularly the invention relates to pencils of this character having amagazine to receive a plurality of leads which may be successivelybrought into writing position as the preceding lead is consumed.

The objects of the invention are to provide a propelling orself-sharpening pencil comprising a casing having an opening in one endthereof for the ejection of a lead, an ejecting mechanism for forcingthe lead through said opening, and a magazine to receive a plurality ofleads arranged between said opening and said ejecting mechanism andhaving a channel or groove in the bottom thereof in substantialalinement with said opening to receive only one lead at a time, theleads falling by gravity into said groove to be propelled by saidejecting mechanism through said opening; to provide a magazine ofimproved construction; to provide an improved combination of themagazine and ejecting mechanism whereby the magazine is always in properrelation to the ejecting mechanism, thus ensuring proper operation ofthe pencil in unskilled hands; to provide improved storage compartmentsfor reserve supplies of leads in addition to the magazine; to provide aconstruction whereby the leads lcan be easily and quickly y transferredfrom said storage compartments F igure'l is a longitudinal sectionalview through a self-feeding pencil constructed in accordance with myinvention;

Figure 2 is a transverse sectional view taken on the line 2 2 of Fig. l,and looking in the direction of the arrows;

Serial No. 457,749.

Figure 3 is a detached perspective view of the magazine, portions beingbroken away;

Figure l is a detail perspective view of the sheet metal member formingpart of the magazine;

Figure 5 is an end view of the pencil with the lead holding and guidingtip removed;

Figure 6 is a transverse sectional view through the magazine taken onthe line 6-6 of Fig. 3, and

Figure 7 is a view similar to Figure G showing a magazine for use with acylindrical casing.

In the embodiment of my invention shown in the drawings, the referencecharacter A designates a tubular casing one end of which is normallyclosed by a removable lead holding and guiding tip B having an axialopening l to receive a piece of lead 2 from a magazine C arranged inlthe casing between the tip B and lead ejecting or propelling mechanismD mounted in the other end of the casing. The casing A may be of anydesired cross-sectional configuration, but in the present instance Ihave shown it hexagonal and having one end formed with a circularportion 23 to receive the adjacent end of the cross-sectionally circulartip B, as shown in Figure l.

The magazine C is constructet to receive a plurality of leads 2, and,when the pencil is held horizontally in proper position, to deposit saidleads singly by the action of gravity each into a position insubstantial alinement with the opening l in the tip B, so that it may beejected by the mechanism D into writing position. To accomplish thisresult in. the construction shown in the drawings, the magazine (l isfni'bstantially V- shaped in cross-section, lia-ving downwardlyconverging sides l along which the leads roll by gravity, in feeding,said sides terminating at their adjacent ends in a groove 5 of a size toreceive only one of the leads 2 at a time. lVlien this magazine is inplace in the pencil, its end next the tip B, as G, is closed only bysaid tip, while the other end thereof is permanently closed, as at 7, toprevent displacement of' the leads. The magazine is of a length slightlygreater than that of the leads 2, and is fitted into the casing A sothat the sides Il: of the magazine form with the wall of' the casing achamber for the reception of lea ds 2, which may be inserted thereinthrough the open end oit the casing and magazine when the tip B isremoved. The underside ot the magazine C is also formed with alongitudinal wing` ,or rib 8 to cooperate with the sides to properlyposition and support the magazine in the casing, said wing also forming'with the casing Ar storage compartments 9 Ytor receiving reservesupplies oit the leads, as shown in VFigures 2 and The groove 5 in themagazine is also arranged in substantial alinement with an ejecting orpropelling rod 1() olf the mes'hanismv l), adapted to slide in saidgroove 5 oil tlle magazine and be reciprocaed by a screw sleeve llrotatably mounted i ially o'lt the casing il. in a tubular bearing linedon the interior olI the casing at its end opposite the tip l, saidsleeve engaging a. tlireruled head on the rod l to :torce the lea-t 2outwardly from the magazine through the opening l in the tip B intowriting position. The screw sleeve 11 is provided with an operating head14; projecting trom the end et the casing at the outer end oli thetubular bearing 12, and at the inner end ol' said bearing is a collarlll tast on the sleeve, so that it can be rota-ted by the head lflwithout any longitudinal movement.

ln constructing the pencil l preferably utilize a tube l5 of a lengthsubstantially equal to the combined lengths et the magazine C and theejecting or propelling rod 19 and having an internal diameter slightlygreater than the diameter ot the leads @ne end ot this tube is threadedtor a short distance, as at 1G, to receive the tip B, and at the innerend of said threaded portion the wall of the tube is cut away, as at17', Figure 3, substantially the length ot one ol' the leads 2 to formthe slot 5 at the bottom et the magazine. rlhis tube receives theejecting or propelling rod l() and extends inside the screw sleeve 11,said rod having at its end away from the magazine a lateral tin 125which projects slidably through a slot in the wall of the tube 15, andis shaped at its outer edge to engage the interior threads ot the screwsleeve 11 and thus be propelled by rotation et the latter. At the innerend ot the magazine C a collar 19 tiXed upon the tube 15, said collarbeing olf a size and configuration to tit within the casing A and. beingsecured thereto, as by a pin 23, said collar Alorming the closed end 7of the magazine. Preferably the magazine C is made Jrom a strip ot sheetmetal 20, ol the same length as the slot '17, bent on its longitudinalcenter and returned upon itselil: to llorm the wing 8, the sides of saidstrip being then curved outwardly apart, as at 2l, to slip over the tubel between the collar 19 and the threaded end 16, and then bent outwardlyat an angle to each other to torni the sides ot the magasine, as shownin Figures .and el. The strip 2O thus shaped is preferably soldered orotherwise rigidly connected to the tube l5 and collar 19, and the wingE3 and sides Ll serve as centering supports Vl'or the magazine in thecasing.

ln use oi my improved pencil, the tip B is removed and the magazine andstorage chambers 9 lilled with leads; then the tip is replaced, and thepropelling rod l() being retracted clear out oit the magazine, thepencil is held horizontal with the magazine '3l in the position shown inFigure 2, so that a lead will tall by gravity into the groove Sonieentcuor indicatinfr 'means .is pro- 2" vided so that the user may .linowwhen the ,magazine is in proper leerling position, such l'or example asa usual pocket clip 2l securedy to the casing so that when uppermost themagazine is in feeding position. `When a lead has ted into the slot 5,which can be facilitated by tapping the pencil gently, the propellingrod 10 is advanced to expose the extremity or the lead for use, as iscommon in pencils of the lead-propelling type. To replenish the leads inthe magazine C it is merely necessary to remove the tip A and transiterleads from the storage compartments 9 or elsewhere to the magazine.

ln Figures 2, 3, 5 and 6 l have shown the collar 19 hexagonal to lit ahexagonal casing, but the collar may be made in any shape to lit aparticular casing, such tor instance as the collar 92 shown in Figure i'which is designed for a casing circular in cross-section.

lVhile l have shown. and described one possible embodiment of myinvention it will be understood that this 's only for the purpose oilillustrating the principles thereof, and that many modilications andchanges can be made in the detail construction of the ini'ention withoutdeparting Alrom the spirit or scope ol "he invention. 'llhereform l donot desire to be understood as limiting myself except as required by theYfollowing clain'is when construed in the light o'lI the prior art.

lv ring thus wh at l cl aim is:

l, lfn a pencil ol' the rliarrwter described, the combination with acasing having an axial opening therein to receive. a lead, of a magazinein said easing to receive a plurality ot leads, said magazine comprisinga tube having an internal diameter slightly greater than the diameter ofsaid leads and having its walls cut away at one side to form a slotsubstantially equal in length. to said leads, and a plurality otlongitudinal wings projecting radially trom said tube to support saidtube in said casing in axial alinement with said opening, two adjacentones of said wings being` arranged on opposite sides oit said slot toreceive said leads therebetween and direct the leads into said slot.

lu a pencil ol the character described deserililed the iuventior lltithe combination of a casing, a longitudinally slotted tube mounted insaid casing and .forming a passageway for a lead, a propelling rod insaid passageway having a lateral head projecting through lthe slot, ascrew sleeve inclosing said tube and engaging said head, a tubularbearing for said screw sleeve held against longitudinal movement in saidcasing, a stop on the screw sleeve at the inner end of said bearing, andan operating head on said screw sleeve at the other end of said bearingand outside of said. easing, said head and stop engaging said tubularbearing to hold said screw sleeve against longitudinal movement in saidcasing.
